A 61-year-old African American man presented with decreased vision of 2 months duration. Examination revealed a significant lenticular astigmatism and sectoral cataract as a result of an amelanotic iris lesion. Slitlamp optical coherence tomography (OCT) revealed angle crowding. An excisional biopsy was performed along with phacoemulsification in the right eye, with intraocular lens implantation for meridional lenticular astigmatism. Histopathology and histoimmunochemistry confirmed a diagnosis of uveal mesectodermal leiomyoma. Lenticular astigmatism may be a subtle sign of an anterior segment tumor. Anterior segment slitlamp OCT is an effective tool in diagnosing as well as monitoring small interval changes in these types of tumors.
一位 61 岁的非裔美国男性出现了 2 个月的视力下降。检查发现，由于虹膜无色素病变，出现了明显的晶状体散光和扇形白内障。裂隙灯光学相干断层扫描（OCT）显示房角拥挤。右眼行切除术活检联合白内障超声乳化吸除术，并植入人工晶状体矫正子午线晶状体散光。组织病理学和组织免疫化学检查证实为葡萄膜中胚叶平滑肌瘤。晶状体散光可能是前节肿瘤的一个微妙征象。前节裂隙灯 OCT 是诊断此类肿瘤以及监测其小间隔变化的有效工具。
